Purpose: Evaluate education equivalence of foreign veterinary graduates
Target Knowledge: First three years of AVMA-accredited veterinary curriculum
Total Questions: 225 (200 operational + 25 pilot)
Time Limit: 220 minutes
Administered: January, May, September
Pass/Fail: Scaled score; varies by exam cycle

SECTION 1: NORMAL STRUCTURE AND FUNCTION (≈48 questions)
---
1. The foramen magnum is located in which bone of the skull?
A) Frontal bone
B) Occipital bone
C) Temporal bone
D) Sphenoid bone
,Answer: B
Rationale: The foramen magnum is a large opening in the occipital bone through which
the spinal cord connects to the brainstem.
---
2. Which structure in the kidney is responsible for the concentration of urine?
A) Glomerulus
B) Proximal convoluted tubule
C) Loop of Henle
D) Collecting duct
Answer: C
Rationale: The Loop of Henle creates the medullary concentration gradient essential for
urine concentration via the countercurrent multiplier mechanism.
---
3. The hormone responsible for stimulating milk ejection (let-down) in lactating mammals
is:
A) Prolactin
B) Oxytocin
C) Progesterone
D) Estrogen
Answer: B
, Rationale: Oxytocin is released from the posterior pituitary and causes myoepithelial cell
contraction in the mammary gland, resulting in milk ejection. Prolactin stimulates milk
production, not ejection.
---
4. Which of the following cell types is responsible for bone resorption?
A) Osteoblasts
B) Osteocytes
C) Osteoclasts
D) Chondrocytes
Answer: C
Rationale: Osteoclasts are multinucleated cells that resorb bone tissue by secreting acid
and proteolytic enzymes. Osteoblasts form bone, osteocytes maintain bone, and
chondrocytes produce cartilage.
---
5. The hepatic portal system carries blood from the gastrointestinal tract to which organ?
A) Heart
B) Lungs
C) Liver
D) Kidneys
Answer: C
Rationale: The hepatic portal vein carries nutrient-rich blood from the GI tract to the liver
for processing, detoxification, and storage before it enters systemic circulation.
, ---
6. Which of the following is a characteristic of cardiac muscle tissue?
A) Voluntary control
B) Multinucleated cells
C) Intercalated discs
D) Lack of striations
Answer: C
Rationale: Cardiac muscle contains intercalated discs, specialized junctions that allow
rapid electrical communication between cells. It is involuntary, uninucleated, and striated.
---
7. The primary function of the large intestine is:
A) Nutrient absorption
B) Water and electrolyte absorption
C) Enzyme secretion
D) Bile production
Answer: B
Rationale: The large intestine absorbs water and electrolytes from remaining indigestible
material and forms feces. Most nutrient absorption occurs in the small intestine.
